5: Summarizing Data with R (with Lucy King)

  • Page ID
    7644
  • This chapter will introduce you to how to summarize data using R, as well as providing an introduction to a popular set of R tools known as the “Tidyverse.”

    Before doing anything else we need to load the libraries that we will use in this notebook.

    library(tidyverse)
    library(cowplot)
    library(knitr)
    set.seed(123456)
    opts_chunk$set(tidy.opts=list(width.cutoff=80))
    options(tibble.width = 60)

    We will use the NHANES dataset for several of our examples, so let’s load the library that contains the data.

    # load the NHANES data library
    # first unload it if it's already loaded, to make sure
    # we have a clean version
    
    if("NHANES" %in% (.packages())){
      detach('package:NHANES', unload=TRUE)
    }
    library(NHANES)
